From 9a3400a4a667e32d1dd0b50364b083787ff63320 Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Fri, 8 Aug 2014 03:23:29 -0400 Subject: Fix some more straggling stuff * HWCODEC bootloaders * Remove references to thread structures outside the kernel. They are private and should not be used elsewhere. The mrobe-100 is an offender that gets squashed. * The ata.c hack stuff for large sector disks on iPod Video gets squashed for the same reason. I will no longer maintain it, period; please find the real reason for its difficulties.
